1 Claim.

Our invention relates to an improvement in hinges. It is well adapted for use in connection with sashes of casement windows or with doors.

One of the objects of our invention is to provide in a novel hinge two pivotally connected leaves, one of which has means by which when the other is swung to a predetermined position, said other hinge leaf may be lowered and held from swinging. Such means provides in one form of our invention for the holding of the swinging leaf in the closed position. In the other form of our invention such means provides for holding the swinging leaf in the open position.

Our invention provides for a sash or door, supported by hinges of one form of our invention, being held thereby from swinging from the closed position. The other form of our invention provides for a sash or door supported thereby being held from swinging from the open position.

A further object of our invention is to provide a hinge, having the novel characteristics mentioned, which is simple, cheap, strong, durable, not likely to get out of order, and which is efiicient in its operation.

The novel features of our invention are hereinaiter fully described and claimed.

In the accompanying drawing, which illustrates two forms of our invention,

Fig. 1 is an elevation of a casement window in which the sashes are supported by hinges, shown reduced in dimensions, embodying our improvement.

Fig. 2 is an elevation of a hinge of one form of our invention, in which the swinging leaf is in the open position and is adapted, when swung to the closed position, to lower and be engaged and held in the closed position by the other leaf.

Fig. 3 is an edge elevation of the hinge shown in Fig. 2, the swinging leaf being shown in the closed lowered position.

Fig. 4 is an elevation of the leaf, shown in Fig. 2, having the slotted knuckle and mounted on the pintle.

Fig. 5 is an elevation of the swinging leaf .shown in Fig. 2.

knuckle, in which the vertical slot in the intermediate knuckle is disposed so as to receive the swinging leaf when the latter is in the open position.

Fig. 11 is a section on the line 11-11 of Fig. 10.

Similar reference characters designate similar parts in the different views.

Referring to the form of hinge shown in Figs. 2 to 9, 1 designates the body or flap of a leaf of the hinge one side edge of which has an upper tubular knuckle 2 and a lower tubular knuckle 3, spaced from the upper knuckle. Intermediate of the knuckles 2 and 3 is a ring like portion 4, which may be termed an intermediate knuckle, which adjacent to the body 1 has through it a vertical slot 5.

6 designates the body or flap of a swinging leaf having at one side edge a tubular knuckle 7 disposed between and alined with the knuckles 2, 3 and 4, and of a diameter such that it will neatly fit in the intermediate knuckle 4.

Through the knuckles 2, 3, 4 and 7 extends a pintle 8 on which the leaf 6 is adapted to swing to and from the open or closed position. In so swinging the leaf 6 rides on the upper edge of the intermediate knuckle l. The width of the slot 5 is greater than the thickness of the body 6 of the leaf, so that when the latter reaches the closed position, shown in Figs. 3, 6 and 8, it will lower through the slot 5, the knuckle 4 so permitting, until the knuckle 7 rests on the lower knuckle 3. The knuckle a will prevent the leaf 6 being turned to the open position, until the latter is again raised to a position in which the knuckle '7 will be above the knuckle 4, as shown in Fig. 2.

When applied to casement sashes 9, Fig. 1, each hinge is fastened, the leaf body 1 to the adjacent inner side of the jamb or stile of the casing, the other leaf body 6 being attached in the usual 5 manner to a vertical edge of the sash 9, and the knuckle 2 being disposed above the knuckle 3.

A space is provided between the upper edges of the sashes 9 and the top rail 10 of the window, so that the sashes may be lifted, when in the closed position, shown in Fig. 1, to permit the leaves 6 of the hinges being raised out of the slots 5. When this is done, the sashes may be swung to the open position. Suitable means, not shown may be provided for preventing the sashes being raised from the outside, whereby they can not be opened from the outside. When the sashes are open and are swung to the closed position, the leaves 6 will aline with the slots 5, and the sashes may be lowered, the leaves 6 entering the slots respectively, thus holding the sashes closed.

In the form of our invention in which the swinging sash lowers and is held open, the construction is the same as that shown in Fig. 2 and already described, excepting that the ring like portion or intermediate knuckle 4, corresponding to the knuckle 4, has its slot 5 located in the side of the knuckle distant from the body 1 of the leaf having the knuckle 4. By means of this construction, the swinging leaf 6 when reaching the open position will enter the slot 5 and will lower therein and will be held by the knuckle 4' from swinging to the closed position, until the leaf 6 is raised out of the slot.

Thus a casement sash 9 provided with the form of hinge having the slot 5 as shown in Figs. 10 and 11, will be held open by the knuckle 4 when swung to a position in which the leaf 6 enters the slot 5'.

By disposing the slot in difierent positions in the knuckle, the sash may be held closed or held open to different degrees. In both forms of our invention, the upper edge of the knuckle 4 and that of the knuckle 4', is wholly in one horizontal plane, whereby when the knuckle 7 and its sash 9 are in the open position, shown in Figs. 2 and 7, the sash does not have to be lifted in order to swing it to the closed locked position, thus making it easy to close. And in the form shown in Figs. 10 and 11, when the knuckle 7 and its sash 9 are in the closed position, the sash does not have to be lifted in order to swing it to the open position. This is of advantage when in cold weather there is ice or snow between the upper edge of the sash and the casing, which condition would render it difiicult to lift the sash.

It will be noted that the knuckle 7, when in the lowered position in the knuckle 4, and also when in the lowered position in the knuckle 4', neatly fits in these knuckles, as is shown in Figs. 7, 8, 9 and 11, whereby the knuckles 4 and 4' will take the brunt of the strain of the weight of the sash, thus relieving the strain on the pintle 8.

It will be further noted that, as shown in the drawing, the lower end of each knuckle 4 and 4' is in the same horizontal plane and contacts with the upper edge of the knuckle 3. By means of this construction the intermediate knuckle is braced by the lower knuckle 3 against a prying pressure upon it and the pintle 8 by a very heavy sash.

We do not limit our invention to the structure shown and described, as other modifications,

within the scope of the appended claim, may be made without departing from the spirit of our invention.

What we claim is:-

A hinge provided with a leaf having an upper tubular knuckle, a lower tubular knuckle, and a knuckle intermediate of said knuckles, and spaced from' the upper knuckle and having its lower edge in the same horizontal plane and contacting with the upper edge of said lower knuckle, and having a slot extending downwardly from its upper edge, a second leaf having 'a body adapted to enter said slot and having a knuckle between said upper and intermediate knuckles and of a diameter such that it will enter and fit neatlyin said intermediate knuckle when said body is lowered into said slot, and a pintle extending through the knuckles of said leaves, saidsecond leaf, when lifted from said slot being adapted to be swung on said pintle while resting on said intermediate knuckle.
